Determination of o-toluenesulfonamide in artificial sweeteners containing saccharin.
J. Assoc. Off. Anal. Chem. 61(6) , 1528-32, (1978) A gas-liquid chromatographic (GLC) procedure with p-toluenesulfonamide (p-TS) as an internal standard is used to determine o-toluenesulfonamide (o-TS), a major impurity in artificial sweetening substances containing saccharin. Although p-TS can itself occur a... |

Distinct reactivity of Pd(OTs)2: the intermolecular Pd(II)-catalyzed 1,2-carboamination of dienes.
J. Am. Chem. Soc. 130(31) , 10066-7, (2008) A Pd-catalyzed intermolecular 1,2-carboamination route to indolines from N-aryl ureas and 1,3-dienes that proceeds under mild conditions in relatively nonacidic media, is presented. The in situ generation, or preformation, of a palladium tosylate emerges as a... |

The allergens of nail polish. (I). Allergenic constituents of common nail polish and toluenesulfonamide-formaldehyde resin (TS-F-R).
Contact Dermatitis 33(3) , 157-64, (1995) Nail polish that has completely dried on the fingernails contains water-soluble components that attain the skin during extensive but transient contact. This was proven by water extraction of thin layers of nail polish that had been painted onto glass plates a... |

Mutagenicity study of Remsen-Fahlberg saccharin and contaminants.
Toxicol. Lett. 7(1) , 51-60, (1980) Saccharin and contaminants of commercial Remsen-Fahlberg saccharin were studied for mutagenic potential with the use of the Salmonella/microsome test, Basc-test in Drosophila melanogaster and micronucleus test in mice. In none of these tests were mutagenic ef... |

Toxicology of saccharin.
Fundam. Appl. Toxicol. 4(5) , 674-85, (1984) Saccharin, like most of the artificial sweeteners, was discovered quite by accident. The controversy regarding its use as a food additive is reflected by the number of chronic/carcinogenic studies conducted to assess its safety. Two chronic studies were condu... |

Behaviour and biodegradation of sulfonamides (p-TSA, o-TSA, BSA) during drinking water treatment.
Chemosphere 71(8) , 1574-81, (2008) Three sulfonamides -para-toluenesulfonamide (p-TSA), ortho-toluenesulfonamide (o-TSA) and benzenesulfonamide (BSA) - have recently been detected in groundwater within a catchment area of one drinking water treatment plant (DWTP), which is located downstream o... |

Ortho-toluene sulphonamide and saccharin in the promotion of bladder cancer in the rat.
Br. J. Cancer 42(1) , 129-47, (1980) The importance of the contaminant OTS in the promoting activity of commercial saccharin on rat bladder neoplasia was investigated. OTS, OTS-free and OTS-contaminated saccharin were administered in the drinking water or diet for 2 years to groups of rats pretr... |

Molecular structure and conformations of para-methylbenzene sulfonamide and ortho-methylbenzene sulfonamide: gas electron diffraction and quantum chemical calculations study.
J. Phys. Chem. A 112(13) , 2969-76, (2008) The molecular structure and conformational properties of para-methylbenzene sulfonamide (4-MBSA) and ortho-methylbenzene sulfonamide (2-MBSA) have been studied by gas electron diffraction (GED) and quantum chemical methods (B3LYP/6-311+G** and MP2/6-31G**). Q... |
